HERNIAL TRUSS.

SPECIFICATION forming part of Letters Patent No. 233,646, dated October 26, 1880,

1 Application filed August 23, 1880. (No inodcl.)

To all whom it may concern Be it known that I, OHARLEs H. TUCKER, of Jordan, in the county ofOnonda-ga,in the State of New York, have invented new and useful Improvements in Hernial Trusses, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The nature of this invention consists, chiefly, in the combination of a truss-band provided with a slotted plate, an arm having likewise a slotted plate and adj ustably secured to the band by a set-screw passing through said plates, and a pad hinged to the aforesaid arm, whereby the hernia is retained with perfect security and with great convenience to the person wearing the truss; and it also consists in certain peculiarities of the detailconstruction of the,aforesaid truss and devices connected therewith, whereby'the adjustmentof the pad is greatly facilitated and rendered more perfect.

In the accompanying drawings, Figure 1 is a front view of my improved truss. Fig. 2 is a longitudinal section on line a: 00; Fig. 3, a transverse section on line yy Fig. 4, atransverse section on line 2 2,- Fig. 5, a detached view of the device by which the pad is connected to the arm of the truss; Fig. 6, an in-.

verted view of the plate which is attached to the arm, and by means of which said arm is connected with the band and pad; and Fig. 7 is a face view of the pad.

Similar letters of reference indicate corresponding parts.

A denotes the truss-band by which thetruss is secured to the person, said band having projecting from its extremity a metallic plate, a, which has a longitudinal slot, 1).

B is a flattened arm applied across the plate a and adjustably secured thereto, said arm having secured to its back an elongated plate,

0, arranged lengthwise the arm and provided with a longitudinal slot, 0, beneath which there is an elongated recess, d, in the arm B.

e is a screw-threaded stud, which is inserted through the slots 1) and 0, respectively, of the plates to and O, and is provided at the under side of the latter with a nut, a, adapted to slide in the recess (7, and prevented from turning by the same. By means of the aforesaid stud the arm B is clamped in its desired posifording perfect adjustment of the pad in its relative position on the band.

The arm B is further secured in its desired positionby a semicircular plate, f, which bears with its straight edge against the edge of the plate a, and is clamped to the plate 0 of the arm by a set-screw, e, passing through a segmental slot, h, in the plate f, and through the slot 0 of plate (J, and provided with a nut, a, on the under side of plate 0. Astud, g, projecting from the center of the plate 1, and passing through the slot 0 aforesaid, serves as a pivot and a guide for said plate. I further increase the scope of adjustment of the plate 0 by providing said plate with a transverse rocker-bearing, i, on the arm B, one form of which bearing is shown in Fig. 40f the drawings, said bearing allowing the arm B to be set at different angles in relation to the plane of the plate 0.

The plate 0 is formed with an eccentric knuckle, K, which projects over the end of the arm B. To the knuckle K is hinged the block D, which is secured in a countersink in the pad P, and has ears 1, embracing the sides of the aforesaid knuckle, and connected with same by a pin passing through said parts. The aforesaid hinge-pin passes through the knuckle at a point forward of the center thereof, so that a follower or bush, 8, in the block D, bearing against the periphery of the knuckle, will bind thereon and arrest the movement of the pad when swung rearward. By means of a set-screw, o, inserted through the rear end of the block D and bearing against the bush 3, the pad can be set at any desired angle in relation to the plane of the arm, as best seen in Fig. 2 of the drawings, and thus brought to bear on the hernia with greater or less force. The pad is also made adjustable in its plane transverse to that of the arm B by providing the block D with a rocker-bearing, m, similar to that of the plate G, as shown in Fig. 3 of the drawings. Said bearing allows the pad to be partly turned side wise and then clamped in its desired position.

By the employment of the arm B, in connection with the band and pad, in the manner described, I am enabled to obtain extra leverage and various degrees of pressure on the pad, and also a better and more convenient application of the pad to the hernia. Furthermore, the extra strain on the hernia incident to sneezing or coughing is counteracted by the pressure of the upper end of the arm B against the bowels. i.

The pad I prefer to construct with a central protuberance, 0, concentric annular protuberance and intermediate concentric depression or concavity, u, as shown in section and plan view, respectively, in Figs. 2, 3, and 7 of the drawings. The central protuberance presses the hernia back into the walls of the bowels, the concavity it packs the flesh around the hernia, and the outer ring, 0, confines said packing.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the band A, provided with the longitudinally-slotted plate a, the arm B, provided with the slotted plate 0, the set-screw e, and the pad P, hinged to the arm B, substantially as set forth.

2. In combination with the bandA, provided with the slotted plate a, the arm B, having the recess d, the plate 0, secured to the arm B and having slot 0, the set-screw e, passing through the slots of the respective plates, and having nut n titted in the recess d, and the pad P, hinged-to the plate 0, substantially as described and shown.

3. In combination with the band A, provided with the slotted plate a, the arm B, provided with the slotted plate 0, the set-screw e, semicircular plate f, provided with the segmental slot h, the set-screw e, and the pad hinged to the plate (J, substantially as described and shown.

4. In combination with the band A, plate a, and arm B, the plate 0, having the rockerbearing t", and the pad P, hinged to the plate 0, substantially as and for the purpose set forth.

5. The combination, with the arm B, of the plate 0, provided with the eccentric knuckle K, and the pad P, provided with the bush 8 and set-screw 11, substantially in the manner and for the purpose shown and set forth.

In testimony whereof I have hereunto signed my name and affixed my seal in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga and State of New York, this th day of August, 1880.
